Abstract
A method for performing remedial cementing operations in a subterranean well includes providing a high density microfine cement composition, the composition having a microfine cement, and a manganese tetraoxide and having a density in a range of 145 to 165 pcf. The high density microfine cement composition is injected into a high pressure zone of the subterranean well. The high density microfine cement composition is pumped into a low injectivity zone of the subterranean well.
